To all 'whom tmay concern:

Be it'lc'nown that I, ALBERT E. KIRK, a citizen of the United States,and a resident of Rensselaer, county of Jasper, and State of Indiana,have invented a new and useful Improvement in Roofing, of which thefollowing isa'specilication, the principle o the invention being hereinexplained, and the best mode in which l have contemplated applying thatprinciple, so as to distinguish it from other inventions. l

Myinvention'relates to improvements in roolings of the prepared or read}'frnade classwhich are put up in the place'whre they are to beapplied. The method of such application; while varying slightly withdifferent' forms-ofthe roofing,- has generally involved simply the4spreading successive sheets of the paperor felt out upon l thereof 'soas to overlap at theajoint, driving rows of nails ortaclis along suchoverlapping portions, and 4then giving'zthe wholea final coating of taror paint.

The-present invention liasregard not only to .the 'maf 4 terial andstructure o f the roofing fabric itself, but also. l toits .form as itleaves the place 'of l manL 1fs4ft1-1re andthe niannerof'i'tsapplication,subsequently, theroof. Said invention,A then, .consists ofmeans hereinafter fuuy'sescnbed snd'psrncuiarly' sa rornh in; theclaims.

' The annexed drawing andfthe followingdescription set forth in detailcertain means embodyingthe invenf tion, such 'disclosed meanx'nstitntipg.but on@ of various'mechanical iorinsiriwhch'the principle of theinvention may be used..

Insaid annexcldrawing'z-lFigure vIfis a perspective lviewef a detachedportion of a roof with my improved roofing applied thereon, suchroofing. being 'brol'en away 'to 'disclose its' structure; and4 Fig. 2,is a. transverse cross-section of such 'roof and applied-roofing, thesec-A tion .being taken' at a joint in'order still more clearly to vshow tlre detailedv construction'of the roofing material,

as also' the manner 'in which I make such joint.

The I naterial character "or rnakefup o1 '1 my rooting will .n iostreadily appearfroma description of one methodpf V'its manufacture, thismethod b eingthe onewhich I ap- -lriiove as producing the best product.In.such-rr'ramu-4 facture I utiliteas the body of my 'roofing a sheet'of roofing' f eltor straw board to the under side of which has beenpasteda lining of Manila paper o1' ordinary newsi lp'aper."Thetthickness' of =such-body layer may vary consid erably `with theparticular use' for which the roo.

' Ving' 'iside-signed., This-felt 'or straw boardl sheet',of

' Coruse, is for reasons o f convenience'in the lform of 'a roll. Suchroll, then, ,is mounted on a reel or othersilitable support from which:it can be u nwound so as to have' thepaper lining on'tlie underside ofthe sheet. A .rollof canvasduck or drilling is similarly-mounted 5-plbovesuch ii'r'stroll so that when'unrolled the strip oireturned toitsproperl place.

be made into rolls whilethe latter material will be superimposed uponthe strip of felt or straw board This canvas or drilling should `beshrunk or ulled by being immersed in water just previously to theoperation here described and will hence 30 inches Wide; Itis thus seenthat .the covering layer` will overlap the. body layer, such over-lapbeing made about twice as great on one side ason the other. Thedisposition of the .two rolls just described is made such Aas to bringthe edge of the sheet of canvas, as it-is unwound, about two inchesbeyond the right-handv edge of y the sheet of felting and about oneinchbeyond the lethand edge. The sheets. thus assembled are nextcemented or bound together and at thesametinrerendered impervious towater by being passed through a tanko suitable water proofing paint suchpaint being of a composition rendering it elastic. even when dry.

Both layers are thoroughlp saturated with this paint andin additionasucient amount is left between themto firmly. cement or paste'therritogetherlA Any surplus of the pai'n't is removed as the strip ofroofing leaves the tank b'y passing the samebetween squeeze rollsas'will "be readilyunderstood. These rolls are so constructed,4

however, as to leavea thicker layer of the paint on the overlappingportions ofthe vcanvas sheet-- As the sheet,

v"built ofv the component parts specilied, leaves the squeeze rolls',the widerover-lapping edge, in'this case the right-hand one, is turnedbaelr'from the 4edge o'f'the body layer so' astolexpose a strip ofthellatteran inc-h in The roofing may now still damp theilsual way,suitable material'being dustedbetween the successive layers yof therolls to prevent .their adhering to each other; or'if desired'it .95instead of being 'roIlod,-a nd bethereupondriedby beg" ingpassed'betwe'en steam rol-1ers .or through a baking 1 i may be cut intostraight strips -of. convenie nt length width.v Such `exposed surfaceisbrushed with? graphite -oroth'er antiadhesve material that prevent thetwo layersfrom sticking together, and thellapof canvas oven.- vI'le'sire to call particular' attention vto "this last form-'oi theroofing. Before baking the sheets, I out away a narrow strip of the bodylayer `at one end 'of the '10o sheetand a wider stripat the other, wheeby flaps ofthe Cover layer of a corresponding width are fortified.The -.balcing processc'auses the bodylayer.ofjeltingto--be come hard andstiff,' and thecoveringlayertop.dh'ere to `it very tenaciously; 1 l Thelatter,- howevenjbecause of ern-ploy'. doesiiot lose its-pliability;4Tlltflstrips th'us lthe before described'characte'r'.ofthe paint whichI.

The finished product when spread out upon the roolin order lo be applied thereto, Figs. -l and 2, is henee seen toeolnprise a portion A, that ('olnprises a sheet ot' rootingr l'elt orstraw-board a and a sheathing o1 Manila orl newspaper n on its underside, and arf-over layer [l ol' eaurnsdduekbr drill. Snell body andeover layers a; .as been explained are thorI oughly saturated with paintof the kind described, but this ypaint appears in appreeiable quantitiesonly between the two layers, as at c and as a light coat t" on the uppersur-lace of the eover layer. llig. 2. 'lhe two [hips ol' unequal widthsformed by theoverlapping portions` of the cover layer appear as b b.rrspeetively.

ln 'applying the rooting it is immaterial win-ther the sheets hedisposed transversely o'r longitudinally o1' the roof, and in laying thesheets transversely one eau in-` dilerently begin at eith'er'end of theroof, just as, in laying them lengitt'ldinally7 one ean commence ateither the comb or the eaves. For the purpose o1' the lfollowingdeseriptionlit is assumed that the lrst method of disposing the sheetsis being followed. It is further'- more assumed that the reeling is putup in the roll form. 'i Such roll, 'then is unwound, and eut into sheetsseveral inches longer` than the distance from the eomb tothe eavesofsuehroof! designated by D, and the Canvas or cover layer is separated lfromthe body layer at each end and the exposed portions of the lat-ter eut.away sofas to leave 'the body layer ol just the right length. Inaddition tothe lateral flaps. b b formed in the pioc'ess of manufacture,llopsof the' textile .cover layerar thus formed at eaeh end, of Vthesevoralsheets, only one b2, however, appearing in the tigu'rrs. i

'.lhefirst sheet to be laid, t", vc. along the outeredge of the roof'is'disposed so as to bring the narrmverflap b of .th'e'lateral flapsalong such edge and tht-corresponding end flap along the eave, the bodylayer being 'These [laps are just flush with the roof in eaeh ease. thenturue'd'over and tal-kerl fast) a coat olthe saune kind; ofpaint as thatwith .which the roolinlor is sat? urated being lirstsp rad alongtherools edge.. From theidisposition ol' the ruiter sheet of rooting asjust dese'ribed it willlie noted' that the wide llap b ol thecoverlayer, the one that is separated l'ronr tlrebodylayer all alongtheedge ot' the` lat-ter, will lie adjm'ent to thenarre'wllalrei the nextsheet ol' rooling. When thisseixmd sheet is spread out. such Wide flapol' th'e. lirsteheet is turned Vback and the sec-:ond sheet thon movedup until 'the edge ol its body layer approaehes, but does not touhA by'some little dist-nnen, the edge of' the bodylayei* of 'the firstsheet'. The two llaps I) end b are'then folded over each other in themanner clearly shown 'in the Figures ofthe drawing. A liberal .coat' o:paint e'r reeling cement being spread between.

the seeeallayers of the joint thus formed, it will be,`

evident-that not only is a perfectly water and air-light informed butone .that will be just as streng as the l-rtdy'ol'the rooting ilsell andno 'more liable to tear. 'Siria-e ive s h'e'ets or strips are applied inthe 'Haine lash-mtheend llaps along the eaves being tat-lied downjl'lsti'as in the ease-of the Iirst strip.` lhe end Ilaps ltttlleritlgeof the rooi are, on one side. of the roof, turned bael-t from th'e bodylayer of the rooting just as the wide-r lateral flap b is turned back,and the/joint or seam along.; suf-h ridge is designed to be made in thesaune way as sueh lateral seams. lly following this nn'lhod ol' layingthe root il will be seen lhal aside from the outer edges ol the rool' nonail whatever needsbe used. ll', however, it be Ilought desirable toemploy nails. as on a steep roof or one ol eonsiderable erw-anse,I theyare driven along th l strip of the body layer that4 is exposed when tlnpb is Iurned baelc, Figs. l and 2. 'lhe flaps are l'olded over and pasteddown in this` event in the saine manner as before. The nails are thusentirely eoyered over and there is no possibility of a leak beingdeveloped at the points where they puncture the rooting as is the easein the types ot' rooting at present in use. rlhe advantage inthus layingthe rootl which is made feasible solar as l am aware by lny roofingalone. is that. all contraction and expansion of the sheets will betaken Vup by the space provided between tlnl several body layers withoutinjuriously wrinkling or doubling.r the latter since, even when thelatter is nailed, the nailing is eontined to one side. The wrin-Idingot' the textile eo ver layer at the joint will be slight in anyevent and have no harmful effect whatever due lo the elnstieity ol' thepaint or cement used. i

when the baked sheet form di rooting,Y is employed the manner ot formingseams between adjaeent sheets is exam-ly the sauro as hns been deseribedin eonne'elion with the applilxation ol the continuous sheet to therool'. Snell sealn will be formed no t only at the meeting lateral edgesol' the sheets but between their ends as wellI whieh, it will beremembered,are formed 'witlrsilnilar llaps. Vlt will ordinarilybeadyisable,

' the wnlerprimed eanvas duck or drilling which 'latter ping the I`Veltor body layer at all. '.lhe latter is thus allowed to rest perleettly(iat upon the root' surl'aee and by leaving spaee between the edges o"adjacent layers provision l'or expansion isnmde and the wrinkling ofytration ol' how my roofing can be made. Also the use ol su'eh rootingfor siding, or in iaet anywhere that prepared rooting has heretoforebeen employed, equally advantageous with its use for rooting Strictly.This last. remark applies particularly to the use of. the baked sheet.torni. el' the rooting, which, by Virtue ofits Stiffness and 4themanner-in whieh'the sheetsare nailed down 'and eem-rund together, adaptssiding thus formed to not only" withstand the weather but also air`pressure l'rom within which latter is frequently en- `eountered whereopen sheathing is used to side up a building.
